The original head temp sensor location for '68-9 (I see your year in 
the subject line now) is under the #4 exhaust port. If yours is still 
there, the wire lead has to bend sharply to clear the heat exchanger. 
It is common for the inner wire to get shorted to ground there.

Grounding will also keep the engine from running.

Starting in '70, the location moved above, near the #4 spark plug. 
Many early cars have had different heads installed to make this move 
possible. If that's where yours is now, grounding is much less 
likely.
